Ultrathink — Cognitive Depth Engine

The thinking depth control system for CoreMind. Five modes, each with explicit activation criteria, quality bars, and tool bindings. Never over-think simple tasks. Never under-think critical ones.

"Depth of thought is proportional to the cost of being wrong."

The 5 Modes

Mode 0: Quick (< 30 seconds)

Activate when:

• Single-file edit with clear requirements
• Lookup (docs, file contents, status check)
• Trivial bug with obvious fix
• Formatting, naming, comment update
